Windows Vista Slow Booup Time

[daniboi81]

I recently reinstalled Windows Visat (about a week or so ago) to refresh my system and start anew. Along with that I also upgraded my computer to 2GB system memory.

In the last couple of days, I've noticed that Windows is starting unusually slow. I noticed it happening yesterday (12/23) and going forward. It will get to the welcome screen then pause for 5 - 10 seconds, then a blank screen (with a movable mouse cursor)...then pause for another 5 - 10 seconds w/ no HDD activity. I used system restore to go back to 12/20/2007 where I knew the system was starting up fine at that time.

I checked system event view and found a few errors on the last couple of bootups.:

Error #1 -- IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 5, function 0. Please contact your system vendor for technical assistance.

Error #2 -- IRQARB: ACPI BIOS does not contain an IRQ for the device in PCI slot 6, function 0. Please contact your system vendor for technical assistance.

I know it's not my memory since I was not having boot up problems after the memory installation and now am at a standstill on what it could be. Below is my current PC specs. I would appreciate any feedback to resove this issue.

Dell Insprion 1501
AMD Turion 64x2 (1.8GHz)
2GB Memory
80 GB HDD
ATI Radeon Xpress Series graphics

Anything in those PCI slots?

I forgot to mention, the computer is a laptop....no PCI slots to speak of.

Are you running the latest BIOS for this? Is ACPI enabled in BIOS?

[daniboi81]

I am using the latest BIOS for this computer. The BIOS itself is very simple and does not have a lot of advanced options that I'm used to seeing when I build a computer.

I assume that ACPI is enabled as the BIOS doesn't indicate either way. Is there something in Device Manager where I can verify this?

In device manger
Look for " Computer" open the subfolder
It should be listed as "ACPI X86 based PC " or something to that affect

You did a clean install
Did you download and install the latest chipset and other drivers from dell?

The ACPI is among those drivers

[daniboi81]

I've verified that ACPI is installed in Device Manager and working properly

I had initially did a clean install of Windows Vista a couple of weeks ago. At that time I downloaded the latest BIOS and updates applicable to my laptop. When I searched available downloads for my model, there was no driver specifically for ACPI.

[Erik]

It would probably be listed as Chipset or Mohterboard drivers. When I look on Dell they list a three drivers under the Chipset section, did you install all three? (They are for different devices).

[daniboi81]

There was only one chipset when I changed the OS from Windows XP to Windows Vista. That chipset driver is for "Ricoh Memory Card Drivers for Vista 32-Bit and XP/2K" which I don't believe I have on this laptop.

I guess I'm wonderning if the slow boot up time would be attibuted to the errors logged in Event Viewer with ACPI. I remember that when I first re-installed Windows Vista, things started up nice and fast. Then something happened about a week after. The only thing I installed after the fact was Office 2007 and not long after Office 2007 SP1.
